Developers hold "TechFugees" conference and hackathon to create apps to address the refugee crisis

The London technology scene is hosting a hackathon to create apps addressing the refugee crisis. The event, called Tech Phew, is personal for some participants, including a former asylum seeker. Teams face challenges like reuniting refugees with family, recording unreported crimes, and giving Syrian refugees a democratic voice. The migration crisis is a major issue, but technology, social media, and smartphones offer new ways to help. Projects include a website providing essential information for refugees and research on migrant smuggling networks. While technology can't solve the entire crisis, it can address smaller issues.
